Special microorganism compound fertilizer for reproduction and growth period of rice

Abstract

The invention discloses a special microorganism compound fertilizer for the reproduction and growth period of rice, and relates to a fertilizer which is made from the following materials: urea, ammonium sulfate, ammonium dihydrogen phosphate, potassium sulfate, magnesium sulfate, calcium nitrate, zinc chloride, copper chloride, manganese sulfate, ferric sulfate, ferrous sulfate, sodium molybdate, boric acid, decomposed farmyard manure, animal viscera leftovers, fermented rapeseed meal, corn straws, filler and a microbial agent. The special microorganism compound fertilizer can effectively improve the ratio of content of each element in the soil, can well fit with the nutrition demand law of the reproduction and growth period of the rice, and can ensure the growth quality of the rice in the reproduction and growth period, the material utilization rate of the fertilizer is enhanced, the rice grain quality is improved, and the special microorganism compound fertilizer has very good promotion use value.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special microbial compound fertilizer for the reproductive growth period of rice. Background technique [0002] my country has a large population but little arable land, and the arable land decreases year by year with the growth of population and the development of industry and cities. Therefore, the only feasible way to increase the output of agricultural products in our country is to increase the output per unit area. In order to meet the demand for agricultural products from industrial development and population increase, chemical fertilizers have been widely used logically. Soil compaction, soil fertility decline, ecological damage, environmental pollution, and quality decline of agricultural and sideline products caused by unreasonable use of chemical fertilizers have been highly valued by relevant state departments and agricultural science and technology circles for a long time.

Problems solved by technology

[0004] The growth of rice can be roughly divided into ten periods, which are: germination period, seedling period, tillering period, jointing period, booting period, heading period, flowering period, milk ripening period, wax ripening period and full ripening period. The milk ripening stage, wax ripening stage and full ripening stage are generally referred to as the reproductive growth stage. Rice has different requirements for large, medium and trace elements in different stages. For example, the demand for nitrogen in the reproductive growth stage is relatively reduced. If according to Applying different fertilizers corresponding to the characteristics of the fertilizer needs in the stage will improve the utilization rate and effect of the fertilizer, but usually for the convenience of fertilization, it is rare to see rice fertilizers targeted at different periods
